New Delhi, Oct 2026 : Sunlight has long been associated with skin damage, premature ageing, wrinkles, sunspots and an increased risk of skin cancer. These concerns have encouraged many people to limit their exposure to the sun by wearing sunglasses, wide-brimmed hats, sun sleeves and other protective accessories. However, journalist Rowan Jacobsen argues in his 2026 book In Defense of Sunlight that excessive fear of sunlight may overlook its potential health benefits.
Jacobsen draws attention to decades of research suggesting that moderate exposure to natural sunlight could support physical and mental well-being. One notable study, which followed nearly 30,000 Swedish women over a period of 20 years, suggested that avoiding sunlight was associated with an increased risk of death, with the potential impact compared in the research to that of smoking.
While such findings do not establish that sunlight avoidance directly causes premature death, they raise questions about whether avoiding the sun entirely is necessarily the healthiest approach.
One of sunlight’s best-known benefits is its role in stimulating the production of vitamin D, which is important for bone health and several bodily functions. Sunlight exposure may also trigger the release of nitric oxide from the skin. This compound helps blood vessels relax and may contribute to lower blood pressure.
Sunlight may also influence mental health. Exposure to natural light can support the body's production and regulation of substances associated with mood and well-being. Some research suggests that sunlight exposure may help reduce the risk of depression, although its effects can vary among individuals.
Another important benefit is the regulation of the body's internal clock, or circadian rhythm. Exposure to natural light during the day, followed by darkness at night, helps maintain the sleep-wake cycle. A properly regulated circadian rhythm can contribute to better sleep quality and overall well-being.
Despite these potential advantages, health experts continue to stress that excessive sunlight exposure can be dangerous. Ultraviolet (UV) radiation can damage the skin, accelerate ageing and increase the risk of skin cancer. Sunscreen, protective clothing and shade remain important safeguards, particularly during periods of intense sunlight.
The challenge, therefore, is to find a balance between enjoying sunlight and protecting the body from overexposure. Seeking shade when feeling overheated and adjusting outdoor activities according to conditions can help reduce risks.
Jacobsen’s central message is that sunlight should not automatically be treated as an enemy. Instead, people should approach exposure thoughtfully, recognising both its potential benefits and its dangers.
His advice is straightforward: “Get sun. Not too much. Go outside.”
